The TC_ACT_REINSERT return type was added as an in-kernel only option to allow a packet ingress or egress redirect. This is used to avoid unnecessary skb clones in situations where they are not required. If a TC hook returns this code then the packet is 'reinserted' and no skb consume is carried out as no clone took place. This return type is only used in act_mirred. Rather than have the reinsert called from the main datapath, call it directly in act_mirred. Instead of returning TC_ACT_REINSERT, change the type to the new TC_ACT_CONSUMED which tells the caller that the packet has been stolen by another process and that no consume call is required. Moving all redirect calls to the act_mirred code is in preparation for tracking recursion created by act_mirred.
